Results: While the under-5 mortality rate was 19.37 per 1000 in 2005, it was 14.31 per 1000 in 2009. Deaths of children
under the age of 5 years took place particularly in Istanbul on the European side (in districts where the land value is low).
Conclusion: Priority should be given to health promotion programs in areas with a low socioeconomic level in particular
where premature death rates are observed to be more common.
